整形激光直接驱动准等熵压缩实验技术对新材料科学、冲击波物理、地球物理学研究等领域有重要意义. 设计特定的实验条件, 可以将材料压缩到冲击压缩和等熵压缩都无法达到的状态, 从而为材料研究提供新的技术途径. 介绍了在神光III原型装置上开展的直接驱动准等熵压缩实验, 对理论基础、实验靶型、实验结果、关键技术、实验特点和数据都进行了较详细的分析. 通过实验和相应的数据处理程序, 获得了加载面上压力超过400 GPa的数据, 这是目前国际上用激光直接驱动的方式获得的Al材料中最高的压力. 同时, 对经过LiF窗口获得的表观粒子速度与真实粒子速度的关系进行了分析, 获得了一条对表观粒子速度进行动态修正的曲线, 从而使粒子速度的计算更加准确. 对实验的改进方向进行了比较明确的分析. 所提供的数据和分析过程对该领域的研究人员有一定的参考价值.Quasi-isentropic compression technique is very useful for new material, shock wave physics, and earth physics. With shaping pulse laser, the quasi-isentropic compression technique is provided. For the designed experimental condition, the high energy density of shaping lasers can be used to generate shockless loading on the solid material to reach a high compression rate state with low temperature, which cannot be obtained with shock compression and isentropic compression technique. Then a new way to study the material can be provided. In this paper, the isentropic compression experiment with laser direct-drive illumination based on Shen Guang-III prototype laser facility is conducted. The theoretical model, target designing, experimental results, key technique, experimental characteristics and experimental data are analyzed in detail. The compression pressure above 400 GPa on the loading surface is obtained with experimental data and processing program, which is the highest pressure achieved to date. After comparing the apparent particle velocity with the true particle velocity, the dynamic correction curve can be obtained to achieve the real particle velocity, which is more accurate. The improving direction is provided, which will provide the important information. The experimental data and design will give the valuable reference for the study in this field.
